+- Do **not** call `POST /api/github/star` on the management API. It refuses
+  agent-driven callers with `403 agent_consent_required`; treat that response as
+  the final answer, not as an obstacle to route around.
+- Do **not** answer the interactive prompt printed by `ocx start` /
+  `ocx service install`. When an agent is detected the prompt is deliberately
+  suppressed and its one-time marker left unwritten, so the user still gets the
+  real question on their own next run.
+- **Do** relay it: ask the user in your reply, and act only on an explicit yes.
+  If they say no or do not answer, do nothing and do not ask again.

+# Zero-leak state stores — implementation roadmap
+
+Opened 2026-08-01. Consumes `000_state_store_inventory.md` (36 stores, verdicts)
+and the prior unit's stream-path work (260731_macos_rss_retention, landed).
+Push to origin/dev is user-authorized for this unit.
+
+## Design goal
+
+Among production TS-based LLM proxies on GitHub, opencodex should have the
+strongest theoretical no-leak posture — while carrying translation duty
+(bidirectional tool conversion, MCP namespace flatten/restore, image
+normalization, reasoning-signature carry) that pure relays do not have.
+The competitive evidence (060) defines "strongest" per category; the phases
+below close every UNBOUNDED and the material CONDITIONALLY-UNBOUNDED verdicts.
+
+## External evidence (Luna lanes, source-opened 2026-08-01)
+
+- Portkey Gateway: no post-stream replay state, but NO upstream abort on client
+  disconnect and unbounded local transform buffers (streamHandler.ts,
+  streamHandlerUtils.ts). No process-wide byte budget.
+- Claude Code Router: per-request AbortController + upstream cancel (good);
+  context-archive store enforces TTL+count+aggregate-body-bytes (the only
+  competitor with a 3-dimension eviction contract).
+- mcp-proxy (punkpeye): replay event store FIFO 1,000 events, no TTL/bytes;
+  session map cleanup only on transport close.
+- LiteLLM: added per-entry max cache item size (v1.63.14) after OOMs;
+  streaming retention issue #6404 open. one-api: externalizes state
+  (Redis/DB), memory cache default off.
+- Eviction-contract precedent: lru-cache maxSize+maxEntrySize+TTL+LRU;
+  cacache for content-addressed disk spill (eviction separate).
+
+Conclusion: no surveyed TS proxy has a process-wide app-owned byte budget.
+Landing one (wp5) plus per-store byte caps positions opencodex to be stronger
+than every surveyed competitor — a claim that stays PROVISIONAL until 060
+supplies the full source ledger (audit round 1).

+### Budget scope split (second-audit R1-6)
+
+The 040 process-wide budget governs EVICTABLE RETAINED stores only
+(continuation, blobs, rings, caches). Translator per-stream buffers and
+serialized-tail backlogs are OBSERVED (high-water fields in appOwnedBytes)
+but never budget-evicted — in-flight conversion state cannot be evicted
+coherently; it is bounded by 050's per-stream caps instead. With this split
+050 is genuinely parallel to 040, and 040's dependency is on the accounting
+hooks of 010/020/035 (030 provides sweeping only, no accounting interface).
+
+### Store-by-store mechanism lock for 030 (S2-5)
+
+| Store | Mechanism | Why |
+|---|---|---|
+| subagent quota-failure records | (a) TTL sweep | getters already treat expired rows as absent |
+| key/combo cooldowns | (a) TTL sweep | same |
+| Anthropic routing health | (a) TTL sweep | same |
+| XAI verdicts | (a) TTL sweep | 30 s TTL with exact-key lazy expiry today (S3-2); reconciliation would leave expired churn until config changes |
+| warning-key memos (all) | (b) reconciliation ONLY | no expiry semantics; TTL would resurrect suppressed warnings |
+| codex quota rows | (b) reconciliation ONLY | 6 h is disk-hydration admission, not a live TTL; live getters serve rows indefinitely (quota.ts:261/298) |
+| provider quota history, model-cache provider history, pool/combo history, guardian backoff, GCP source tokens, ownership/PID memos, OAuth/reauth keys | (b) reconciliation | dead keys unreachable from current config/accounts |
+| Windows ACL success memos | (c) delete-after-rename | R1-2 contract; destination re-keying forbidden |
+
+Scope guards: provider adapter LOGIC unchanged (bounds are added at the
+adapter-local accumulation sites without altering event semantics — the
+"translation duty" stores are bounded, never deleted); #820 architecture
+(turn lease/session lanes/scheduler) stays out; stream-path work from the
+prior unit is not reopened.
+
+## Locked design decisions
+
+1. **Continuation (010):** keep the store authoritative for replay; single
+   oversized entries spill to a DEDICATED per-entry file (not the debounced
+   monolithic snapshot, which is async/best-effort/2 MiB-skipping — R1-2).
+   Demotion ordering is locked: RAM row becomes a stub ONLY after an atomic
+   successful spill (write-fsync + atomic NO-REPLACE publication — link or
+   exclusive copy; plain rename replaces existing destinations and is
+   unsuitable, 010 round-6). Spill FAILURE (disk permissions,
+   exhaustion, I/O) evicts the row from RAM and records a small
+   `spill-failed` tombstone for the response id: later continuation
+   against it returns a terminal structured 400 telling the caller to resend
+   the full context without `previous_response_id` — caller-driven recovery,
+   not an automatic client fallback. Replay through a missing/
+   corrupt stub likewise returns an EXPLICIT structured continuation error,
+   never silent forwarding of the naked delta. The last-entry exemption is
+   deleted; `storedResponseBytes > byteCap()` always spills or
+   tombstone-evicts within a bounded in-flight window — the RAM cap is
+   unconditionally hard.
+   UNSAFE boundary: if spill-through cannot preserve replay, stop and report
+   rather than truncating conversations.
+2. **Blobs (020):** per-blob admission cap + aggregate byte cap with LRU;
+   eviction split by provenance (R1-3): locally-regenerated blobs (root/turn,
+   rebuilt each request per protobuf-request.ts) are LRU-evictable; REMOTE
+   `setBlobArgs` blobs are pinned within TTL — evicted only at TTL expiry
+   unless protocol-level re-send is proven by regression. The aggregate cap
+   is enforced AT INSERT for every provenance: if admitting a remote
+   blob would exceed the cap after evicting all evictable entries, the
+   insert is REJECTED and the hash takes the explicit-miss path (identical
+   protocol surface to an evicted-hash miss) — pinning orders eviction
+   preference, it never overrides the cap. Explicit miss on
+   evicted hash. Antigravity inner maps get count+byte bounds with
+   clear-on-invalid preserved. Image zero-weight sentinels get key-byte
+   accounting and a count cap (R1-1).
+3. **Sweeper (030):** ONE shared `sweepExpired()` utility with per-store
+   registration, run on a coarse timer (60 s, unref) and on store-write —
+   but with THREE mechanism classes per the 030 matrix (R1-4): clock-TTL
+   predicates, config-generation reconciliation for generation-owned keys,
+   and admission caps for active resources. No behavior change for live keys.
+   Windows ACL success memo: evict the temp-path row after rename completes;
+   never let one temp's success vouch for another (R1-5, security review).
+4. **Budget (040):** observability FIRST (appOwnedBytes payload), then a
+   documented demotion contract: when the global budget is exceeded, evict
+   oldest unpinned entries store-by-store in a fixed priority order
+   (logs/rings → caches → blobs → continuation spill). Never reject new work
+   admission as the first lever.
+5. **Translator bounds (050):** aggregate-byte caps sized for 20+ parallel
+   tool calls as NORMAL (per prior handoff): per-call args cap 2 MiB, per-turn
+   aggregate 32 MiB, overflow FAILS the turn coherently (never truncated JSON).
+   Cursor frame admission rejects announced sizes above cap before buffering.
+
+## Open questions carried into phase docs
+
+- 010: spill file naming/GC — per-entry content-addressed vs id-keyed files;
+  orphan cleanup on startup. Decide in the phase doc after reading the disk
+  path (the debounced snapshot is NOT reused for spill — locked, R1-2).
+- 040: budget default size and config surface (fixed vs configurable).
+- 050: which tails (image/oauth/grok) get admission caps vs busy-rejection.
+
+## Regression-class requirements per phase (audit round 1)
+
+- 010: spill durability-before-demotion; missing/
+  corrupt spill → explicit error; spill-failure tombstone eviction + counter;
+  restart replay; provider metadata + tool-
+  result replay through stubs; replacement/TTL cleanup of spill files; orphan
+  cleanup; concurrent flush/demotion; disk-permission failure.
+- 020: local vs remote blob provenance; exact boundary admission; aggregate
+  accounting; replacement/re-store LRU; explicit misses; Antigravity live-call
+  preservation; image sentinel metadata accounting; pinned-saturation
+  (remote blobs collectively at cap → new inserts rejected with explicit miss).
+- 030: fake-clock global expiry; live-key preservation; generation
+  reconciliation; timer singleton/unref/stop; write-trigger sweep; Windows
+  repeated-temp ACL proof (second temp for same destination is re-hardened).
+- 035: subscriber admission cap (rejects beyond cap, existing listeners
+  unaffected); active-registry admission counter + leak metric monotonicity;
+  active-registry HARD admission cap (beyond-cap request receives a coherent
+  busy error, existing work unaffected — S3-3); flight staleness (a stuck
+  flight is replaced, not joined, after the guard) plus bounded
+  distinct-grant admission (concurrent grant fingerprints capped — S3-3);
+  usage-read bounded parse (oversized log yields a capped result,
+  not an unbounded in-flight value); discovery response byte cap +
+  concurrent-gather cap; OAuth pending-code value cap + flow/probe admission;
+  MiMo JWT byte cap; MCP payload caps; value-byte truncation for crash-ring,
+  fixed-slot diagnostics, and affinity entries (truncated string still
+  useful, marker appended).
+- 040: observe-only metrics; exact replacement/eviction accounting; pinned/
+  no-evictable fallback; single-entry-over-budget; privacy-safe payloads.
+- 050: 20+ interleaved calls normal; per-call and aggregate boundaries;
+  coherent overflow (no truncated JSON, turn fails); upstream cancellation;
+  Cursor announced-frame rejection before allocation; queue ordering/
+  backpressure; stalled-tail busy/admission.
+- 055: max-live admission; idle + absolute lifetime termination; session
+  ownership (no cross-session kill); controlled termination drains output;
+  disabled-by-default posture unchanged.
